摘要

背景：慢性阻塞性肺疾病（COPD）与左心房（LA）功能障碍相关，这可能导致不良的心血管结局。本研究探讨了新发现的形态学-电压- p波持续时间心电图（MVP ECG）评分对COPD患者早期LA功能障碍的预测价值。方法：在这项横断面研究中，101例COPD患者入组。所有患者均接受斑点跟踪超声心动图检查，并根据其LA功能分为两组。结果：我们的研究结果表明，COPD患者的峰值心房纵应变（PALS）值存在显著差异，LA功能正常组的平均PALS为28.74±1.81%，LA功能异常组的平均PALS为18.44±1.87% (p)结论：MVP心电图评分有望作为COPD患者心房重构的早期检测工具。

Identifying early left atrial dysfunction in COPD patients using ECG morphology-voltage-P wave duration score

Background

Chronic Obstructive Pulmonary Disease (COPD) is associated with left atrial (LA) dyfunction, which may contribute to adverse cardiovascular outcomes. This study investigates the predictive value of lately identified morphology-voltage-P wave duration electrocardiography (MVP ECG) score for detecting early LA dysfunction in COPD patients.

Methods

In this cross-sectional study, 101 COPD patients were enrolled. All patients underwent speckle tracking echocardiography and were classified into two groups based on their LA functions.

Results

Our findings demonstrate significant variations in Peak Atrial Longitudinal Strain (PALS) values among COPD patients, with a mean PALS of 28.74 ± 1.81 % for the group with normal LA function and 18.44 ± 1.87 % for the group with abnormal LA function (p < 0.001). Despite similar LA diameters across groups, these variations indicate subclinical LA pathogenesis. ROC curve analysis indicated that an MVP ECG score greater than 2.5 predicted abnormal LA function with a sensitivity of 65 % and a specificity of 91 % (area under the curve [AUC]: 0.873; p < 0.001), suggesting its utility in identifying atrial damage and remodeling.

Conclusions

The MVP ECG score shows promise as a tool for early detection of atrial remodeling in COPD patients.
